The is based on a combination of our own experience, consultation and investigative research, and often leads to the preparation of advisory publications and manuals, including case studies of good practice. Internationally, we have been at the forefront of work on tourism sustainability, for the UN World Tourism Organization, the European Commission and other agencies, drawing on experience from around the world. In the UK, we have worked for government departments, RDAs and others on a wide range of issues concerning the successful planning, organisation and delivery of tourism.
